Lesson Plan | Active Learning | Kinematics: Vertical Motion

Assumptions: This Active Lesson Plan assumes: a 100-minute class, prior student study with both the Book and the start of Project development, and that only one activity (among the three suggested) will be chosen to be conducted during the class, as each activity is designed to take up a significant portion of the available time.

Objectives

Duration: (5 - 10 minutes)

This stage of the lesson plan aims to establish clear and specific objectives that will guide students in studying vertical motion. By making explicit what will be learned, students can better focus on the fundamental aspects of kinematics and how to apply them to practical problems, preparing them for classroom application activities.

Main Objectives:

1. Empower students to calculate distances in vertical motions, including the total distance traveled, using kinematic formulas.

2. Teach students to determine final velocity and displacement time in situations of vertical motion, such as the free fall of an object.

Introduction

Duration: (15 - 20 minutes)

This stage of the lesson plan aims to engage students with problems that encourage the review and application of prior knowledge in kinematics, specifically in vertical motion. Through problem situations, students are challenged to think critically about how to apply studied formulas and concepts. The contextualization, in turn, aims to show the relevance and applicability of vertical motion in the real world, increasing student interest and connection with the material.

Problem-Based Situations

1. Imagine that an object is dropped from the top of a building and another is launched vertically upwards from the ground at the same time. How could we use the motion equations to predict when both will be at the same height?

2. Consider a ball being thrown upwards. What factors determine the time it will take to return to the ground, and how can we calculate its speed at the highest point of its trajectory?

Contextualization

The study of vertical motion is crucial not only in physical theories but also in practical applications such as aerospace engineering and sports. For instance, calculating the trajectory of rockets or the performance of athletes in sports involving jumps are direct applications of kinematic concepts. Furthermore, understanding concepts such as acceleration due to gravity and air resistance is essential for comprehending natural and technological phenomena.

Development

Duration: (70 - 80 minutes)

The development phase aims to place students in practical situations where they can apply the theories and equations of vertical motion learned. By working in groups to solve problems and carry out creative activities, they develop collaboration skills, critical thinking, and practical application of theoretical knowledge. Each activity is designed to be fun and educational, ensuring that kinematic concepts are deeply understood and retained effectively.

Activity Suggestions

It is recommended to carry out only one of the suggested activities

Activity 1 - The Rocket Race

> Duration: (60 - 70 minutes)

- Objective: Apply vertical motion equations in a practical and fun context, stimulating collaboration and critical thinking.

- Description: Students will be divided into groups of up to 5 people to design and simulate the launch of a paper 'rocket'. They will use vertical motion equations to predict the maximum height the rocket will reach and the total flight time.

- Instructions:

• Each group will receive materials to build their rocket (paper, scissors, tape).

• Groups should apply the vertical motion equations to calculate the maximum height and flight time, assuming an initial speed that will be measured at launch.

• Launch the rockets and record the results.

• Compare the calculated results with experimental results and discuss the differences.

Activity 2 - Jump to Victory

> Duration: (60 - 70 minutes)

- Objective: Understand how vertical motion equations apply in everyday and sports activities, promoting learning through practice.

- Description: In this activity, students will calculate the height and flight time of a vertical jump. Each group, using one member as the 'athlete', will measure their own performance and apply motion formulas.

- Instructions:

• Choose a volunteer from each group to perform a vertical jump.

• Measure the flight time with a stopwatch from the jump until the return to the ground.

• Use the measurements to calculate the maximum height achieved by the jump.

• Discuss how vertical motion equations apply to human movement and compare results between groups.

Activity 3 - Parachuting Egg Challenge

> Duration: (60 - 70 minutes)

- Objective: Explore the influence of air resistance on vertical motions and apply kinematic knowledge to solve a practical and challenging problem.

- Description: Groups of students will design a parachute for an egg using lightweight materials and calculate the safe descent time to prevent the egg from breaking upon reaching the ground.

- Instructions:

• Build a parachute using plastic bags and string, attaching it to an egg.

• Calculate the expected descent time using vertical motion formulas with air resistance.

• Drop the egg with the parachute from a predetermined height and measure the actual descent time.

• Evaluate the accuracy of the calculations and the effectiveness of the parachute in protecting the egg.

Feedback

Duration: (10 - 15 minutes)

The purpose of this feedback stage is to consolidate the knowledge gained through reflection and sharing experiences lived during practical activities. By discussing in groups, students can learn from each other, identify common errors, and clarify doubts, thus strengthening their understanding of vertical motion kinematics concepts and their application in real situations. This stage also serves to assess students' understanding and adjust future approaches on similar topics.

Group Discussion

To initiate the group discussion, the teacher should encourage students to share their experiences and discoveries from the practical activities. A brief recap of the learning objectives can begin, followed by asking each group to present their results, challenges faced, and learning outcomes. It is important for the teacher to guide the discussion to emphasize the application of kinematic formulas in the real world and how discrepancies between theory and practice can occur and be resolved.

Key Questions

1. What were the biggest challenges when applying vertical motion formulas in practical activities?

2. How did real conditions differ from the ideal conditions assumed in the equations?

3. What did you learn about the kinematics of vertical motion that was not clear just from theoretical study?

Conclusion

Duration: (10 - 15 minutes)

The purpose of this conclusion stage is to ensure that students have clearly understood all the concepts discussed during the lesson, linking them with practical examples and demonstrating their relevance in the real world. This moment also serves to reinforce learning by reviewing key points and preparing students to apply this knowledge to future academic and professional challenges.

Summary

To wrap up, we will summarize the main concepts of Kinematics covered today, focusing especially on vertical motion. We will revisit the formulas for calculating distances, final velocities, and displacement times, and how these apply to practical cases such as the fall of objects or vertical launches.

Theory Connection

Today's lesson was designed to connect theory with practical activities, allowing students to see the direct application of vertical motion equations. Activities such as building and launching paper rockets and the parachuting egg challenge served to illustrate how the studied theory manifests in practice, providing deeper and more engaged learning.

Closing

Understanding vertical motion is essential not only for the study of physics but also for practical applications in daily life, such as in engineering, sports, and even in everyday situations involving the analysis of movements. This knowledge helps to form a solid foundation for future studies in physics and other applied sciences.
